3 claims. (c1. 25e-'145) I This invention relates to a portable winch,and especially to a winch for use in laying pipe lines and the like. l

The general object of the present invention is J to provide an improvedwinch of rugged construction, in which the members which are subjectedto greatest wear and strain are readily replaceable.

A further object of the present invention is to i provide a portablewinch, which maybe positoned astride a trench or like excavation andwhich will be especially adapted for raising and lowering objects suchas a pipe line into and out l of the trench, which winch will be soconstructed 1'5 as to be comparatively light in weight and at the sametime extremely rugged, to enable the handling of comparatively heavyloads.

Another object is to provide a winch for raising and lowering objects inand out of a trench,

which winch will be so constructed that it may be dismantled formovement or shipment from one place to another and when dismantled maybe readily stored and yet which winch may be assembled by unskilledlabor.

Other objects and features of this invention will become more apparentfrom the following description, reference being had to the accompanyingdrawing, in which I illustrate a preferred embodiment of the invention.

In the drawing, Fig. 1 is a plan View of my improved winch construction;Fig. 2 is a side elevation of the winch, certain parts being broken awayto more clearly illustrate the internal construction; Fig. 3 is afragmentarysection of the winch, on an enlarged scale, the plane of thesection being indicated by the line 3 3 on Fig. 1.

The winch, as shown in the drawing, is supported by a pair of spacedframes A adapted to be positioned at opposite sides of a trench. Eachframe has the base I0 in the form of an inverted channel and extendingupwardly and inwardly therefrom are three struts or tubes which, attheir upper ends, are connected with a horizontal tube II which extendstransversely over the trench. Two of these struts, shown as I2 in thedrawing, are secured to opposite ends of their base I0, and extendupwardly to the outer end of the tube II, while the third strut I4extends from the center of the base I0 and is connected to the inner endof the tube II. As shown in the drawing, a suitable reinforcing band i5encircles the tube II at the inner end, and the strut I4 is secured tothis band. Suitable cross-bracing, such as tubes I6, extend between thestruts I2 and strut I4, while other braces, such as tubes Il', extendfrom the strut I4 to the outer end of the tube il. The various elements,tubes and the like, which form the frames may be secured in any wellknown manner, preferably, however by welding. welds forms the subjectmatter of my copending application for Letters Patent filed October 1,1938, and assigned Serial No. 232,729. Briefly, this method when appliedto winch frames contemplates welding the upper ends of the struts 10` I2and Ill to the faces of the channel members I8 and then welding thelongitudinal edges I9 of the flanges of the channel members to the sidesof the tubular member to which the strut is joined. The reinforcingmembers are welded to 15 the struts in a similar manner.

The frames A are joined together by a member which also supports a cablewinding drum 30. As illustrated, the tubes II are slid onto the oppositeends of a connecting shaft or tube 25. 20 When the member 25 is a tube,as shown, the ends thereof may be closed by closure plates 26 and weldedto the ends of such tube, and arranged to abut the respective closureplates 2|] which are secured to the outer ends of each tube II, there 25by to maintain the inner ends of the tubes II a predetermined minimumdistance apart. It will be noted that the external diameter of the tube25 is substantially the same as the internal diameter of the tubes I I,thus the former tube not only 30 joins the two frames A, but in additionreinforces the tubes II.

The frameconnecting tube or member 25 is removably secured in positionwithin the tubes I I in any well known manner, such, for instance, 35 asby the set screws 2l' as shown in Fig. 3.

The cable winding drum 30 is rotatablyl mounted on the member 25,between the inner ends o1' the tubes II. Axial movement of the cablewinding drum 3D is restricted by the inner faces 32 40 of the tubes II,which as heretofore described are maintained a minimum distance apart byreason of the supporting end of the tubes 25 and l I, and coact with hubformations 33 of the drum.

The driving mechanism for the winch is best 45 shown in Fig. 2. 'I'hecable drum 30 is provided with an internal gear ring 35, which may besecured to the drum by means of bolts 36. Meshing with this gear ring isa pinion 31, which is secured to a shaft 38, the inner end of which is50 mounted in a bearing 39. This bearing may be clamped. in place on oneof the two frame members I I or secured thereto by Welding, as indicatedin the drawing. I'he outer end of the shaft 38 is journalled in a gearbox 40, which likewise 65 The method of making the 5l may be removablysecured to a tube Il or may be welded thereto. Secured to the shaft 38,within the gear box 40, is a, worm wheel 4I, which is engaged by a wormgear 42 mounted on a crossshaft journalled in the gear box and to whichis secured an operating crank 45, thus enabling the operation of thehoist from a point adjacent the side of the trench.

From the foregoing description it will be seen that I have provided avery simple, light and yet rigid construction and by utilizing the shaftwhich rotatably supports the winding drum `as a tie between thesupporting frame members A, the winch may be readily dismantled forpacking in a relatively small space. tates replacement of the drumsupporting shaft which due to the fact that the drum is rotatablymounted thereon, and the fact that the shaft provides the only tiebetween the two supporting members A, is practically the only membersubjected to any substantial wear or stress.

I claim: Y 1. In a winch, a pair of frame members, each frame membercomprising an elongated base and a tube, said tubes extending in adirection normal to their respective frame members, tubular strutsinterconnected between opposite ends of the base and the outer end ofsaid tubes, a tubular strut connected between the mid-point of each baseand the inner end of the respective tube, a cross brace between saidstruts and between said struts and said tube, a reinforcing memberencircling the inner end of said tube, a shaft having its opposite endsextending into the tubes of respective frame members, said shaft formingthe only nterconnecting member between the two frame members, and acable winding drum rotatably mounted on said shaft and provided with hubmembers engaging the inner ends of said tubes and reinforcing members.

2. In a winch, a, pair of frame members, each member having an elongatedbase at its lower This also faciliend and a tube at its upper end,tubular struts interconnected between opposite ends of the base and theouter end of said tube, a tubular strut connected between the mid-pointof said base and the inner end of said tube, cross bracing between saidstruts and between said struts and said tube, a cap secured to the outerend of said tube and a reinforcing member encircling the inner end of ysaid tube, a shaft having closed ends extending into the tubes ofrespective frame members and engaging the caps of respective tubes tomaintain the inner ends of said tubes a predetermined minimum distanceapart, and a cable winding drum rotatably mounted on said shaft andprovided with hub members engaging the inner ends of said tubes andreinforcing members.
